FAQ
- How long should a UI success sound be?
- Usually under one second. Entries here range from a few hundred milliseconds to about half a second.
- Are these realistic instrument recordings?
- No. They are synthesised in Python (numpy/scipy) from written prompts, not sample libraries.
- Can I match these to my brand palette?
- Copy the prompt and code, change seed or timbre targets, and re-run the runner to iterate.
